Types of Antibiotics

The
different types of antibiotics are arranged according
to their effective range in the antibiotics list.

Tetracyclines
are commonly used type of antibiotic and are considered to be effective against
the Gram positive and Gram negative
bacteria. These antibiotics are also effective against psittacosis and
rickettsias. Ciprofloxacinis another effective type of antibiotic in the
antibiotic list which can be used for mild infection treatment of sinuses and
urinary tract. Penicillin, erythromycins and the cephalosporins are medium
spectrum antibiotics and are very effective against the Gram positive bacteria.
Polymyxins
are considered to be narrow spectrum antibiotics because these can be effective
against few species of bacteria.

Tetracycline

It belongs to the
bacteria of genus Streptomyces. These
types of antibiotics in the antibiotic list are very effective against Gram positive and Gram negative bacteria
which can interfere with protein synthesis. Rickettsial
bacterial infections like Rocky mountain spotted, respiratory, urinary
infections, intestinal, some eyes, acne and other diseases can be treated with
this antibiotic. There can be permanent teeth discoloration with tetracycline
and pregnant and lactating should not use it. There is loss of the usefulness
of these antibiotics because of strains development of microorganisms
resistant.

Bacitracin

Bacitracin is another
type of antibiotic which is produced by bacterial strains Bacillus subtilis. Topical therapy like for eye and skin infections
can be treated with this antibiotic as it is included in the antibiotic list. This
antibiotic is very effective against gram positive bacteria. It should not be
used internally as it is toxic to humans.

Erythromycin

Erythromycin is one of
several types of antibiotics in the antibiotic list which is produced by the
bacteria of genus Streptomyces. It is
very effective against the gram positive bacteria like streptococci, pneumococci and staphylococci. It is also effective
against gram negative bacteria and some fungi. There is protein synthesis with
erythromycin in susceptible microorganisms. Diseases like syphilis infections,
pneumonia due to fungi, streptococcus can be treated with this antibiotic.

Streptomycin

This type of antibiotic
is produced by the soil bacteria of genus Streptomyces.
This antibiotic is effective against gram negative and gram negative bacteria
including the species resistant to the antibiotics like penicillin,
streptococci and bacteria. This antibiotic is effective against the tubercle
bacilli. It is normally used by combining one or more drugs ehtambutol,
isoniazid and aminosalicylic acid. This antibiotic is included in the
antibiotic list as well.

Cephalosporin

This type of antibiotic
is related to more than 20 antibiotics in the antibiotic list derived from
genus Cephalosporium of fungi and it chemically related to penicillin as well.
This antibiotic can act against gram positive and gram negative bacteria by
inhibiting cell wall synthesis. It can be used to treat meningitis, gonorrhea
and staphulococcal and other infections which can not be treated with
penicillin. There can be increased bacterial resistance to drugs with overuse
of cephalosporins.
